The client application would still need to render its ui and other stuff
through the traditional means, of course.
There are a lot of ifs in there though, so it is just thoughts for now :)

Hi Luca,

If the ShaderEffectSource depends on itself, it needs to have the “recursive”

probably want is to set “layer.enabled: true; layer.smooth: true” on the

I see.. So if this pattern is more common then perhaps a different strategy is
in order. Thinking out loud:
One option we could implement is to have a hint on the canvas that it should be
retained. Meaning, when the application is hidden and the scene graph and the
GL context is invalidated, we

I couldn't reproduce a crash with 50 consecutive open/cancel, so I'm thinking
this will be fixed in the next update then.

Hi,
I'm hoping this will already be fixed in update 9 by the cleanup improvements I
did to the canvas implementation a few weeks ago, but just to be on the safe
side, I'd like to test it. Is there an example or app I could try to verify
that? (I'd prefer to get a complete example rather than re

You are only affected if you use QtQuick in combination with OpenGL and the QSG
classes.
Raw OpenGL, SDL, etc is not affected.

lcontext.html#aboutToBeDestroyed is
something something you can already do. Same if you want to avoid the issue all
